What is a .csproj.user file?

File Extension Details

The .csproj.user file is a specialized configuration file used by Microsoft Visual Studio to store user-specific settings for a C# project. While the primary .csproj file contains build instructions and file references shared across a development team via source control, the .user file is intended to store local preferences that vary from one developer to another. These settings typically include debugging configurations, such as the specific start action, command-line arguments, working directories, and target URLs for web projects. It also tracks the state of the IDE for that specific project, including window positions and which files were last open. Because these settings often contain absolute file paths or environment-specific configurations that would not function correctly on a different machine, the .csproj.user file is almost universally excluded from version control systems like Git or Subversion. If the file is missing or deleted, Visual Studio automatically regenerates it with default values the next time the project is opened and modified, ensuring that the core project remains functional without requiring the local user data.
